University of California, San Francisco Identifier:
First received: December 26, 2009
Last updated: December 28, 2009
Last verified: December 2009

This study objectives are the following.

  • To describe the updated clinical presentation, indications, and multidisciplinary medical management of patients with a failed and/or complicated jejunoileal bypass (JIB).
  • To analyze the feasibility, safety, and efficacy of one-stage laparoscopic re-operative gastric bypass surgery for failed and/or complicated Jejunoileal bypass (JIB) for weight loss.
  • To determine what factors or strategies are associated with a successful outcome. In particular, the completion of the surgery in one stage with a laparoscopic approach.

Ages Eligible for Study:   18 Years to 65 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Patients who underwent laparoscopic revision of JIB to Roux-en-Y gastric bypass (RYGB) for poor weight loss or JIB-related late complications were analyzed. Failed or JIB-related late complications, mostly metabolic, were considered for surgical intervention after optimized medical multidisciplinary management

Inclusion Criteria:

  • Met NIH criteria for weight loss surgery with poor weight loss after JIB
  • Intractable, severe and/or recurrent JIB-related late complications after optimized medical management
  • Laparoscopic approach for primary revisional bariatric surgery

Exclusion Criteria:

  • Any other type of revisional bariatric procedure
  • Open approach for revision surgery
  • missing records and/or unreachable patients with scant information for analysis
